Mantle Convection Animation

Continental drift animation centred on the uk duration.

Mantle convection animation. Plate tectonics is a direct consequence of this convection. The circulation that results from hot rising material and cool sinking material is. Mantle convection cells and continental driftwmv. Early textbooks showed mantle convection cells like in a beaker of hot liquid on a bunson burner pushing plates along from below.

Convection in the mantle certainly plays a role but doesnt explain how some plates move faster than the convective currents beneath them. It illustrates a mathematical model of how convection might occur in the mantle. What are convection currents.

This animation shows a cross section of earth. The relative velocity between plates causes crustal deformation at the boundaries between plates. Diagrams of convection cells in the mantle are often highly simplified but researchers are finding that the real world is much more complex. It was once thought that mantle convection could drive plate motions.

The earths surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantlethe lithosphere is divided into a number of plates that are continuously being created and consumed at their. Transport of heat from the interior of the earth drives solid state convection. When a solid liquid or gas is heated it expands becomes less dense and rises. Mantle convection is the very slow creeping motion of earths solid silicate mantle caused by convection currents carrying heat from the interior to the planets surface.

Scientists study mantle convection or the flow of hot rock in the earths deep interior in order to better understand how this flow shapes the surface of the earth. Thermal structure from models of mantle convection with surface plates temperature dependent and radially stratified viscosity more info this animation shows the evolution of thermal structure within the mantle over a period of about 4 transit times equivalent to 200 ma. Mantle convection and plate tectonics provide a general framework for understanding tectonophysics. Thermal convection in the terrestrial planetary mantles the rocky layer be tween crust and core inwhich hotmaterial rises cold material sinks and the induced ow governs plate tectonic and volcanic activity as well as chemical segregation and.
